I watch The Simpsons in French and I often hear some informal expression, but I can't figure out how one writes them.
What is an informal word for a tv set in French (like telly) ? Homer (main character) calls it like "téléch". How this word is written?
From time to time characters express their agreement with an expression that sounds like "ok, dack".

What he pronounces exactly?
